The Sennheiser HD 201 are below-average headphones that feel cheaply made and have an unexciting sound. They only passively isolate, which lets noise seep into your audio in loud environments and on noisy commutes. However, they will remain stable on your head even during physical activity.
The Sennheiser HD 201 are very stable headphones that feel comfortable and do not apply much pressure to the head. Sadly, the all-plastic build quality and weak hinges may not last as long as other headphones. They have no control options for your audio, and the cable is non-detachable. They also look a little bland aesthetically.
The HD 201 are lightweight and do not apply much pressure to the head. The oval ear cups are large enough to fit well around the most listener's ears. Unfortunately, they do not have enough padding on the headband and the ear cups, which reduces their level of comfort.
The Sennheiser are not the most portable headphones. They are mid-sized over-ear headphones but do not fold up into a smaller format for easy transport or lay flat to take up less space. They will fit in a backpack but are little too cumbersome for handbags and purses and will not fit into most pockets, even larger jacket pockets. They also don't come with a case or pouch which is disappointing.
The HD 201 are very stable headphones. Once on the head they barely move even during physical activities like jogging. They maintain their position extremely well during casual listening sessions, and although they are not designed for use while doing sports, they will not slide off your ears easily even after a violent shake. Unfortunately, the cord is not detachable, which may pull the headphones off your head if ever it gets hooked on something.
The Sennheiser HD 201 is a average sounding pair of closed-back over-ear headphones. They have a very good Bass, a decent Mid Range and an average Treble. However, their Bass delivery is quite inconsistent and could vary noticeably from person to person. Also, their Mid Range is overemphasized and their Treble tends to sound forward and sharp. Additionally, they have a mediocre Soundstage and poor distortion performance which could make their sound harsh and brittle.
The frequency response consistency of the HD 201 is mediocre. These headphones showed about 6dB of deviation in bass delivery across our 5 human subjects. This is significant and noticeable, however, their treble delivery is decently consistent.
These headphones isolate passively, which means they do not actively cancel any ambient noise that seeps into the ear cups. Although the ear cups' seal around the ear is decent, it's not sufficient to block the level of ambient noise in loud environments like in a train or plane. They are not ideal for commuting or traveling but won't disturb people around you too much because of their relatively low leakage.
Poor isolation. These non-noise cancelling headphones don't isolate any sound below 1KHz. The passive isolation provided by the ear cups is also below average. It starts to kick-in around 1KHz, reaching the maximum of -30dB at 6KHz.
Decent leakage. The majority of the leakage is happening in the mid and treble regions, spanning from 500Hz-3KHz. Although this range is rather broad, the overall level of the leakage is not too loud.
